Formal and Real Authority in Organizations

GAICIL Insights

The boss holds the title.¹ Whoever holds the information often holds the decision. Formal and Real Authority in Organizations, by Philippe Aghion and Jean Tirole, develops a theory distinguishing formal authority, the right to decide, from real authority, the effective control over decisions. It shows how a formally integrated structure can accommodate various degrees of real integration.

Real authority is set by the structure of information, which in turn depends on the allocation of formal authority. A principal with formal authority may defer to a better-informed subordinate, handing that subordinate real authority. More real authority for the agent promotes initiative but costs the principal control. That tradeoff is the heart of organizational design.

When does delegation make sense? Delegating formal authority eases the agent's participation and fosters the incentive to acquire relevant information, at the cost of lost control. Formal authority is therefore more likely to be delegated for decisions that are relatively unimportant to the principal, where the principal can trust the agent, that matter to the agent, and that are innovative enough that the principal has not built substantial prior expertise. Novelty pushes power downward.

Communication bends around authority too. Centralization, the non-delegation of formal authority, may jeopardize communication by making the agent worry about being overruled, though it can favor communication when the agent trusts the superior. Who holds the right to decide shapes how much the organization learns.

Several forces raise a subordinate's real authority inside a formally integrated structure: overload, lenient rules, urgency of decisions, reputation for moderate interventionism, performance measurement and multiple superiors. A principal with a large span of control cannot monitor every decision, so subordinates gain effective control. The authors present the paper as a first step toward a general theory of authority and its delegation.

Artificial intelligence rewires the information structure at the center of the theory. Better information and analysis in the principal's hands could raise the principal's real authority and reduce reliance on subordinates. AI tools in subordinates' hands could widen their information advantage and real authority. The same technology can centralize or decentralize; deployment decides.

The innovation result is the sharpest prediction for AI adoption. Adoption involves many novel decisions where principals lack prior expertise. The theory predicts organizations will delegate authority over AI implementation to those with relevant knowledge, promoting initiative and information acquisition. The executive who insists on approving every AI choice may be the bottleneck.

The framework also covers delegating decisions to AI systems themselves. Organizations choose which decisions to automate and which to keep under human control. The initiative-versus-control tradeoff applies: delegating to AI may gain speed and information processing and lose control. The paper's factors, such as decision importance and trust, offer a checklist for the choice.

Communication matters for learning. Subordinates who fear being overruled may stay silent about how AI could improve operations. Structures that build trust and delegate appropriately help organizations learn about and benefit from AI. Silence is the hidden cost of a heavy hand.

Overload and urgency matter more as AI speeds things up. Faster decision cycles may push real authority toward those closest to operations. AI-enabled performance measurement could also raise subordinates' real authority by making their contributions more visible. Faster clocks redistribute power.

Seen whole, the paper's message is plain: formal and real authority differ, and real authority follows information. Delegation buys initiative and information acquisition at the price of control. As AI reshapes information flows, this framework explains how authority will shift and how organizations can design structures to capture the technology's benefits.

Something for leaders rolling out AI to sit with: the org chart will not tell you who decides once the tools spread. Ask where the information now sits, and you will find where real authority has quietly moved, whether that was the plan or not.
